APPARATUS FOR CONVEYING THE EXHAUST GASES OF AN INTERNAL-.COMBUSTION ENGINE FROM A GrARAJLTl.`

Application filed April 16, 1925. `Serial No. 23,549.

To all' whom t may concern.'

Be it known that'J I, FRANK S. BALATTA, a citizen of United States, residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented certain new and useful Improvements in Apparatus for Conveying the Exhaust Gases of an Internal- Combustion Engine from a Garage; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My present invention has for its object to provide a safe andhighly efficient apparatus for conveying the deadly exhaust gas of an internal combustion engine, when stationed in a garage or other building, to the outside thereof.

To the above end, the invention consists of the novel devices and lcombinations of devices hereinafter described and defined in the claims.

In the accompanying" drawings, which illustrate the invention, like characters indicate like parts throughout the several views.

Referring to the drawings:

`Fig. 1 is a view partly in central vertical section and partly in diagram showing a garage and a motor-propelled truck having the invention embodied therein;

Fig. 2 is a plan view of the apparatus with some parts broken away and other parts sectioned on the line 2 2 o-f Fig. 1, on an enlarged scale;

Fig. 3 is a view partly in left side elevation and partly in vertical section taken on the line 3--3 of Fig. 2; and

Fig. 4 is a view corresponding to'Fig. 3 but showing the frame yof the apparatus collapsed.

The numeral 5 indicates a garage having at one end a door 6 and at its other end a stop block 7 Within the garage 5 is an internal combustion-engine-propelled Jtruck 8, the driving shaft case and exhaust pipe of which are indicated by the numerals 9 and 10, respectively. A `muiiier 11 is interposed in the exhaust pipe 10. The parts thus far described have been illustrated simply `for the purpose of showing the invention applied in working position.

Interposed in. the exhaust pipe 10 forward of the muffler 11 is a cut-out including a T- shaped casing 12 having an exhaust port 13 connected by a short hose section 14 to an underlying forwardly projecting exhaust nozzle 15. f This exhaust nozzle 15 is held suspended fromthe driving shaft casing 9 by a pair of hanger brackets 1G. In the discharge end of the exhaust nozzle 15 is a conical spider 17. Mounted in the cut-out casing 12 is a hinged valve-acting blade 18 having on its hinge pin a crank arm 19. The valve-l acting blade 18 is actuated by a spring 19 to close the exhaust port 13 to the nozzle 15 so that normally the exhaust gases pass through the cut-out casing 12 to the muffler 11. For operating thevalve-acting blade 18, to close the exhaust pipe 10 tothe muffler 11 and thereby cause the exhaust gases to pass through the port 18, hose 14 and nozzle 15, I provide a vertically` disposed tripping lever 2O intermediately pivoted to the forward hanger brackety 16 and having its short or upper end connected by a cable 20 to the crank arm 19. This tripping lever 20 is gravity-held and automatically operated in a manner that will hereinafter appear.

Supported on the floor of the garage 5 is a collapsible frame comprising a skeleton rectangular base 21 to the corners of which are pivoted four uprightposts 22, opposite pairs of which are connected by front and rear tie rods 23. These two tie rods 23 are connected at their ends by a pair of end tie bars 24 and which in turn are connected by an intermediate angle bar 25.

' The collapsible frame is rigidly secured to the floor of the garage 5 by lag screws 26 and is arranged to be collapsed by a swinging movement toward the front of said garage. Stop lingers 27 on the rear pair of posts 22 are arranged to engage the floor of the garage 5 and limit the collapsing movement of the frame. The collapsible frame is provided with a pair `of 4counterbalancing springs 28 anchored to the rear posts 22 and the upturned rearwardly extended end portions of `the end members of the frame base 21.

Overlying the tie rods 23 is a carriage 29 which, as sho-wn, is in the form of a flat p-late having depending apertured ears 30 through which said rods project to afford track rails on which said carriageis free tended neck 34 to which lis attached 1a hose which lies in an open trough 36 in the floor of the garage 5 and extends outside of said Vgarage through one side thereof.-

The exhaust head 32 is pivotally attached to the carriage 29 by a bail-like member 37 pivoted to depending ears 38 on the bottoni of the carriage A29 for vertical swinging movement. The intermediate` portion of the bail 37 is contracted onto the sides ofthe neck 34 and which neck is pivoted thereto at 39. rThe bail 37 holds the exhaust hea-d 32 for movement transversely of the tra-velling movement of the carri-age 29. `A pairl of coiled springs 40 anchored to ther abutment plates 31 and attached to the exhaust mouth 33, yieldingly hold `the exhaust head 32 drawn forward with the mouth resting on the carriage y29 `as a stop. A torklike plate 41 secured to the carriage 29 holds the exhaust head '32 lagainst lateral -movement but with freedom for 'the pivotal and Y, lifting movements, as permitted by t-he bailn having their adjacent endsconnected.

like member v37.

The carriage 29:.isyieldingly held lin central position and returns to the position by a coil-ed spring42 and a cable T e other end `of vthe spring 42 is anchored to the frame angle bar k25 and the other end of thel cable 43 is attac-hed at 44 to the carriage 29. Said cable43 is arranged to run over a pair of guide sheaves 45 journaled on the frame angle bar 25. These guide sheaves 45 are so .arranged as to cause the spring 42 to ieturn A the carriage 29 to a central or normal position when said carriage is moved either to the left or right.

Normally the frame is collapsed, as shown in Fig. 3, and to automatically .set the same up, `under a movement of the tru-ck 8,. there is provided a depending swinging arm 46 pivote'd to a .clamp 47 applied to the propeller shaft casing 9. A T-shaped hook 48 is pivoted to the free or lower Aend Iof .the arm 46 and is yieldingly held in an intern'iediate position by a` Icoiled spring 49 anchored to said arm. `Thisfhook 48 is arranged to engage an upstanding bail 50 which spans the abutment plates 31 and is rigidly secured to the carriageQQ, and set up the collapsed frame during the movement of the truck 8 into the 'garage 5. The bail 50 is' vfurther held by brace bars 51 ancho-red tothe carriage 29. Chains 52 attached to the rear posts 22 and anchored to the frame base 21 act as stops for the frame during `its ksetting-up movement.

O pemtz'on.

As previously stated, the frame is normally collapsed, as shown in Fig. 3. During the forward movement of the truck 8 into the garage, the hook 48 engages the bail 50 and lifts the frame until stopped bythe chains' 52. -Alt the time the upsetting movement of the frame is stopped by the chains 52, thehook 48 is tripped out of engagement with ithe bail 50 and the released arm 46 swings i-nto a vertical position. At the completion of the setting up of the flame, the exhaust nozzle 15, under the lcontinued forward lmovement of the truck 8, enters lbetween `the abutment plates 31 and if said nozzle is not aligned with the flaring mouth 33 of the exhaust head kr32, it eng-ages either one ofsaid abutment lplates and thereby shifts the carriage 29, against the tension of the spring 42, to align said mouth so that the exhaust nozzle 15 will enter the same, kas shown in'Fig. 3. As the exhaust nozzle 15 `enters vthe mouth 33, the same is engaged thereby and the exhaust head 32 moved slightly rearwardly on its pivot 37 so as to form a tight joint between the exhaust nozzle 15 and the exhaust hea-d 32. At this time, the front wheels of the truck 8 engage the stop block 7 and properly position said truckin respect to the apparatus for conveying exhaust gases. The -conical spi-der 17 assists ,in cen-tering the exhaust nozzle 15 in the'exhaust head 32 so thata tig-ht joint will be formed therebetween. During the movement of the exhaust nozzle 15 between the abutment plates 31, the lever 29 engages the front edge portion of the carriage2-9 and is tripped thereby to open the valve-actingy plate'18, as shown by full lines in Fig. 3Vand thereby close the exhaust pipe 10 to the muiller 11 and direct the exhaust gases through the port 13, hose 14, nozzle 15 where the same is conveyed by the hose 35 outside of the garage 5. After the valve-acting plates 18 have been opened, the same is held open. by the tripping lever 2O which is held .he 4carriage 29.

`Then the truck 8 is backed from the garage 5, the exhaust nozzle 15 is withdrawn from the exhaust mouth 33 and .from between the abutment plates 31, and at which time the springs 40 return the exhaust head 33 to normal position and the spring 42 returns the carriage 29 to its norma-l posit-ion. During t-liisinovement of the truck 8, the tripping lever 20 slides out of engagement with the 'carriage 29 and. together with the valve-actinglplate 18 are returned to normal positions under lthe action of gravity.

During further backing movement of the truck 8 from the garage, the hook 48 .e11-

gages the bail and collapses the frame, the movement of which is stopped by the iingers 27 coming int-o contact with the floor of the garage 5. lVhen the frame is stopped by the fingers 27, the hook 48 is tripped out of engagement with the bail 50 and thereby releases the arm 46 to permit the same to swing into its normal position and thereby completes the resetting of the movable parts of the apparatus.

By changing the operative length ot the stop chains 52, the carriage 29 may be set at different elevations for vehicles of ditte-rent makes and the counter-balancing springs 28 will hold the collapsible frame Wherever stopped by said chains.
